Which of the following is NOT a result of using forage crops?

Using forage crops typically leads to several beneficial outcomes, including increases in both soil fertility and soil quality. Forage crops are often utilized in crop rotation and cover cropping systems, contributing organic matter to the soil, which enhances nutrients and helps in retaining moisture. Moreover, they improve soil structure and promote microbial activity, which are vital for healthy soil ecosystems.

Concerning water drainage, forage crops can actually improve drainage in certain contexts. Their root systems can create channels in the soil, allowing for better infiltration and reducing issues related to waterlogging, which enhances overall soil health. This contradicts the notion that forage crops worsen water drainage.

Lastly, forage crops can pose challenges related to crop diseases. However, the diverse planting and rotation practices associated with forage cropping systems typically reduce the overall risk of disease in other main crops. Therefore, the correct answer highlights that worsening water drainage is not a result of using forage crops, as the use of these plants tends to have a positive impact on drainage and overall soil health.
